It's been my experience that "beer..more beer.." during fabrication and welding means that tomorrow starts with re-doing... Hope that's not the case for you!!
I think I'll go see if I can shovel my way into the garage - again.
When it comes to replacing floor pans .... i recommend that folk take the grinder, make the first cut ... go have a beer ... then if your stress level is back down, come back and do more ... other wise, enjoy another beer and finish cutting it tomorrow. That first cut is usually what breaks people
